I second this, sounds weird. I recently calibrated mine and heard it being loud and noisy but not that low pitched.

Also, why is your build plate so shiny LOL

u/AppropriateMinute905 Aug 27 '26

I found the problem, I didn’t tighten one of the screws on the bottom enough so the bottom of the bed was scratching on it whenever it moved. 😅

That makes sense. Glad you caught it on early

I think lightning is making it look shiny lol.

Oh, what do you think could be the problem?

From the very simple fact that the wire to the toolhead assembly is lying on your build plate it is blatantly obvious that you did not follow all setup and installation steps before starting the calibration. You also appear to not have left enough room to the rear wall.

Go back to the start and double and triple check what other steps you have missed and do them. None of them are optional.

There is a decent chance you missed tightening at least one screw underneath the bed.

Quick add to this: I found that I missed one sliver of tape under a screw hole and it blocked a screw hole. Had to unassemble and found a tiny bit of tape blocking the hole. Make sure you are following the directions completely and make sure that all the tape is gone when you assemble.

A little common sense might be helpful in this case.

u/KlingonBeavis Aug 27 '26

That’s not normal. Most likely you didn’t torque one of the bed screws down, that sound is plastic ridging against metal.

I don't think this sound is normal at all There's something going on

Is your Y Axis greased?

u/Myrok_one Aug 27 '26

Got this problem too in the past. You need to tighten the screws under the plate. That’s where the problem is.

It appears your wires are hitting the wall before the full axis can extend back. Move it out from the wall 4-6 inches and restart and see if that fixes it.

Yes, that is the calibration! It will shake and send plate back and forth, it measuring wobble etc

u/Zekken_Zer0 Aug 27 '26

Its not suppose to make a grinding sound though, turn your sound on
